6.3 IR Spectrum and Characteristic Absorption Bands

The band intensity is in a medium to weak level. The alkynes can generally be identified with the characteristic weak but sharp IR absorbance bands in the range of 2100–2250 cm-1 due to stretching of the C≡C triple bond, and terminal alkynes can be identified by their absorbance at about 3300 cm-1 due to stretching of sp C-H.

Analyzing Infrared Spectra - Course Hero

The IR spectra of two compounds can also be analyzed and compared to track the progress of a reaction. For example, the oxidation of cyclohexanol (C 6 H 11 OH) to cyclohexanone (C 6 H 10 O) converts an alcohol to a ketone. The two key functional groups in this reaction are the alcohol ( {\rm {O {-}H}} O−H) and the ketone ( {\rm {C {=}O}} C=O ).
